## Overview

A vector store stores [embedded](/oss/integrations/text_embedding) data and performs similarity search.

    subgraph "📥 Indexing phase (store)"
        A[📄 Documents] --> B[🔢 Embedding model]
        B --> C[🔘 Embedding vectors]
        C --> D[(Vector store)]
    end

    subgraph "📤 Query phase (retrieval)"
        E[❓ Query text] --> F[🔢 Embedding model]
        F --> G[🔘 Query vector]
        G --> H[🔍 Similarity search]
        H --> D
        D --> I[📄 Top-k results]
    end
```

### Interface

LangChain provides a unified interface for vector stores, allowing you to:

- `add_documents` - Add documents to the store.
- `delete` - Remove stored documents by ID.
- `similarity_search` - Query for semantically similar documents.

This abstraction lets you switch between different implementations without altering your application logic.

### Initialization

To initialize a vector store, provide it with an embedding model:

```python
from langchain_core.vectorstores import InMemoryVectorStore
vector_store = InMemoryVectorStore(embedding=SomeEmbeddingModel())
```

### Adding documents

Add `Document` objects (holding `page_content` and optional metadata) like so:

```python
vector_store.add_documents(documents=[doc1, doc2], ids=["id1", "id2"])
```

### Deleting documents

Delete by specifying IDs:

```python
vector_store.delete(ids=["id1"])
```

### Similarity search

Issue a semantic query using `similarity_search`, which returns the closest embedded documents:

```python
similar_docs = vector_store.similarity_search("your query here")
```

Many vector stores support parameters like:

* `k` — number of results to return
* `filter` — conditional filtering based on metadata

### Similarity metrics & indexing

Embedding similarity may be computed using:

* **Cosine similarity**
* **Euclidean distance**
* **Dot product**

Efficient search often employs indexing methods such as HNSW (Hierarchical Navigable Small World), though specifics depend on the vector store.

### Metadata filtering

Filtering by metadata (e.g., source, date) can refine search results:

```python
vector_store.similarity_search(
  "query",
  k=3,
  filter={"source": "tweets"}
)
```

<important>
Support for metadata-based filtering varies between implementations.
Check the documentation of your chosen vector store for details.
